HARRY LEONARD MARTIN, OF LANCASTER, PENNSYLVANIA.

COMBINED GRAIN SEPARATOR AND SlVlUTTER.

SPECIFICATION forming part of Letters Patent No. 312,369, dated February17, 1885. Application filed April 30, 1884. (No model.)

T0 on whom, it may concern.-

Be itknown that I, HARRY LEONARD MAR- -TIN, of Lancaster, in thecountyot Lancaster and State of Pennsylvania, have invented a new anduseful Improvement in Combined Grain Separator and Smutter, of which thefollowing is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a partoi'this specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a sectional side elevation of my improvement. Fig. 2 is anend elevation of the same, parts being broken away. Fig. 3 is asectional end elevation of the same, taken through the line 00 m, Fig.1.

The object of this invention is to facilitate the cleaning of wheat andother grain, and promote thoroughness in such cleaning; and to this endit consists in the peculiar construction and arrangement of parts, ashereinafl ter fully described, and pointed out in the claims.

A represents the frame of the machine, to which is attached the casingB. To the top of the frame A is attached a box or casing forming achamber, 0, for the rotating screen D, the shaft E of which revolves inbearings in the ends of the chamber 0. The screen D is formed with six(more or less) ribs, D, and its covering is made of wire-cloth orperforated sheet metal, and in three sections,123. The upper or headsection, 1, is made with such a fineness of mesh or perforation as toallow only the dust and fine sand to pass through. The middle section,2, is coarser. so as to allow cockle-seed and otheriine seeds topa-ssthrough. The lower or tail section, 3, is the coarsest, and is designedto allow the grain to pass through. The tailings escape from the openlower end of thescreen D. The screen D is made with an annular head, Dthrough the open center of which passes the feed-spout F, through whichthe grain is introduced into the said screen. The bottom of thescreenchamher 0 isv made with five hopper shaped recesses, G H I J K.The recess G is at the head of the screen D, and is designed td receivethe scatterings from the feed-spout F and the screen D and dischargethem into the graindischarge-chamber L in the lower part of the head endof the machine. The re cess H is beneath section 1 of the screen D, andreceives the dust and sand that escape through the said section, thesaid dust and sand passing through the spout M into the chamber N in thelower part of the machine. The recess I receives the screenings from themiddle section, 2, of the screen, which screenings pass through thespout 0 into the small chamber P, attached to the side of the casing ofthe exhaust-fan Q, and opens into the said exhaust-fan. as shown in Fig.3. The recess J receives the grain from the tail sections 30f thescreen, which grain falls into the well R, and is removed therefrom inthe manner hereinafter described. The recess K receives the tailingsfrom the screen D, which tailings pass through the spout S into somesuitable receiver.

From the recess J of the screen-bottom a spout, T, leads to thedust-chamber P, so that the exhaust-fan Q will withdraw the dust fromthe screenchamber G and well B.

To the casing B,at the other side of the exhaust-fan Q, is attached adust-chamber, 1?, andwhich opens into the said exhaust-fan Q and intothe chamber N, so that the said exhaust-fan Q, can withdraw the dustfrom the said chamber N.

l/vithin the chamber N is placed a hollow cylinder, U, the shell Vofwhich is perforated at its head part with small holes or slots, and atits tail part with larger slots, as shown in Fig. 1. The ends of theshell V are secured by long bolts 7 against the heads X X, the saidbolts passing through lugsformed upon the edges of the said heads. Theheads X X are formed with projecting cylindrical chambers Y Y upontheirmiddle parts, and upon the ends of the said chambers are formedhollow gudgeons Z Z, which revolve in hearings in the frame A, and serveas journals to the cylinder U. The hollow gudgeons Z Z serve as bearingsto the shaft a, which passes through them through hearings in the frameA, and to,

which, within the cylinder U, is attached acylinder, I).

To the cylinder b are attached radial arms or teeth a, which arearranged in a spiral row, as shown in Fig. 1, and are made of such alength that their outer ends will be close to the inner surface of theshell V, as shown in Figs. 1 and 3.

To the shaft (1 are attached spiral flanges d (1, extending from theends of the cylinder 11 to the outer ends of the cylindrical chambers YY, the flange cl being designed to feed the grain into the cylinder U,and the flange d being designed to feed the grain out of the saidcylinder.

In the wall of the cylindrical chamber Y, which passes through the wellR, are formed three (more or less) openings, 6, which are covered bycups or buckets f, which, as the cylinder U revolves, take up thegrainin the bottom of the well It, and cause the said grain to pass throughthe openings 0, so that it will be fed by the spiral flange (1 into thesaid cylinder U.

In the wall of the cylindrical chamber Y are formed two (more or less)openings, c, through. which the grain as it is fed into the said chamberby the spiral flange (1' falls into the discharge-chamber L, and escapesthrough the opening in the bottom of the said chain'- her. The dustbeaten from the grain by the teeth 0 escapes through the-holes or slotsin the cylinder-shell V, the heavier particles escaping through theopening 9 in the hoppershaped bottom of the chamber N, and. the lighterparticles being drawn out by the exhaust-fan Q.

To one end of the shaft a'is attached a small pulley, h, to receive thedriving-belt, and to the other end of the said shaft a is attached asmall pulley, 1', around which passes a belt, j. The belt j also passesaround a larger pulley, 76,. attached to the end of the screen-shaft E.To the other end of the screen-shaftE is attached a small pulley, Z,around which passes a belt, m, which also passes around a larger pulley,n, attached to the projectingendof the hollow gudgeon Z. By crossing oneof the beltsj m the cylinder U will be driven in the opposite directionfrom the shaft carrying cylinder b. By making boththe belts j onstraight the cylinder U and the shaft carrying cylin- I the shaft of theexhaust-fan Q, so that the said exhaust-fan will be driven from theshaft a, but at a greater speed.

Having thus described my invention, Iclaim as new and desire to secureby Letters Patent- 1. Ina grain separator and smutter, the combination,with the hollow cylinder U, having a perforated and slotted shell, andprovided -with the end chambers, Y Y, having open-v ings e e and bucketsf, of the cylinder 1), arranged within the cylinder U, and provided withthe spirally arranged teeth 0 and the spiral flanges d d on its shaft a,substantially asherein shown and described.

2. In a grain separator and Sin utter, the combination, with thecylindrical chamber Y, having side openings, 0, and the bucketsf, of thegrain-receiving well R, substantially as herein shown and described,whereby the grain will be fed iutothesmutter, as set forth.

3. Ina grain separator andsmuttelgthe combination, with thescreen-chamber O and the smutter-chamber N, of the exhaust-fan Q, thedust-chamber P, and the spouts O T, substantially as herein. shown anddescribed, whereby the dust and screenings will be withdrawn from themachine, as set forth.

4. A grain separator and smutter comprising the screen-case O, therecesses G H I J K, the revolving screen D, the cylinder U V, providedwith the chambers Y Y, the cylinder I), provided with thespirallyarranged teeth 0 and the spiral flanges d d on its shaft a, andthe exhaust-fan Q, all arranged and combined substantiallyas hereinshown and described.
